STARTECH M.2 to U.3 Adapter NVMe expansion card

SKU CH-PPEK-HXZGC

Connects an M.2 NVMe SSD to a U.3 (SFF-TA-1001) port for expanded storage capacity

  • Product typeAHCI SSD Adapter
  • Add NVMe storage via a U.3 port using an M.2 drive
  • Supports M-Key PCIe x4 M.2 SSDs for fast data access
  • Compatible with U.3 SFF-TA-1001 connectors on servers or workstations
  • Operates reliably from 0 °C to 50 °C (32 °F to 122 °F)
  • Withstands storage extremes of -40 °C to 85 °C (-40 °F to 185 °F)

M.2 NVMe to U.3 adapter

This StarTech adapter connects an M.2 NVMe M-key PCIe x4 solid-state drive to an available U.3 (SFF-TA-1001) port on a computer or server. It adds storage capacity without replacing the existing drive or chassis. The board is classified as an AHCI SSD adapter and operates between 0°C and 50°C.

Developers and creators adding fast storage

The adapter suits developers and content creators who need extra NVMe capacity for data-intensive workloads. It is not for systems that lack a U.3 backplane or cable, nor for drives that use a different M.2 keying or protocol. Buyers without a compatible U.3 connection should look at other options.

M-key PCIe x4 to U.3 (SFF-TA-1001)

The single deciding specification is the M.2 M-key PCIe x4 to U.3 (SFF-TA-1001) interface pairing. Only NVMe drives with that exact keying and lane configuration will function. Verify the drive and host port match before purchase.

Questions about this item

How do I install the M.2 NVMe SSD into the adapter and connect it to the U.3 port, and what step do people often miss?

Insert the M.2 NVMe SSD into the M-Key slot at an angle, secure it with the mounting screw, then plug the adapter into the U.3 (SFF-TA-1001) backplane; the step often missed is fully tightening the retention screw so the drive stays seated under vibration.

What maintenance or replacement will this adapter need over time?

The adapter itself has no moving parts or wear items, so it requires no scheduled maintenance; only the installed M.2 NVMe SSD may eventually need replacement based on its own endurance rating.

What thermal limit appears first during sustained heavy I/O?

The operating range tops out at 50 °C (122 °F); sustained workloads that push the adapter or the installed SSD beyond that temperature will trigger throttling or shutdown before any other limit is reached.
